ABSTRACT:
A fuel emulsion consists of diesel, water and an emulsifier composition having a hydrophile/lipophile balance value of at least 4. The emulsifier composition comprises a polymeric non-ionic surfactant having hydrophilic and hydrophobic repeating units together with at least one component selected from fatty acid esters or partial esters of polyhydric alcohols; alkoxylated fatty acid esters or partial esters of polyhydric alcohols; and alkoxylated primary alcohols. Preferred emulsifier compositions according to the invention include mixtures of the polymeric non-ionic surfactant with at least two of the components. Especially preferred compositions comprise mixtures of the polymeric non-ionic surfactant with the fatty acid (partial) esters or alkoxylated fatty acid (partial) esters. The emulsifier composition may include an emulsion coupler such as a primary alcohol, e.g. octanol.
